RivaTuner Fan Speed Adjustment

I'm looking for a way to set the minimum fan speed for a Nvidia gpu, using the latest version of RivaTuner.

I see settings all over for RivaTuner for setting the fan duty cycle, which I'm using now, (that is, one for the board itself, and one setting for fan duty cycle for the driver), but is there another setting just for fan speed?

The "Power User" section is somewhat of a wash because clicking many of the help book icons, just brings up the message "file not found".

direct control sucks, set up dynamic fan speed, all my nv cards since g92 do it, idle 35%-40% depending what i want to hear and hit 100% at 60c, and its gradual increase/decrease works flawlessly.

Some people (including myself and the OP) have problems with the dynamic speed. Mine (on a PNY 9800GT 1GB) stays at 40% and goes up to 80c, where it will usually EUE. My EVGA 8800GS 384MB seems to control just fine and doesn't usually go over 65c.

When you're folding you have a constant, or nearly so, load on the GPU. As a result, there is very little need to have anything but one setting. The fan is going to have to run at the same speed constantly to maintain a given temperature so the end result will be the same on auto as it would be in direct control. Setting the duty cycle in RivaTuner directly sets the fan rpm. 90&#37; duty cycle runs the fan at 90% max rpm, 80% duty cycle runs the fan at 80% max rpm....
